Titan 806-091 Spacer (replaces Titan 0551535)

Spacer 806-091 (replaces Titan 0551535) for airless sprayers

The 806-091 spacer is a mechanical component used to establish and maintain precise gaps between parts within the drive system or pump assembly of compatible airless sprayers. It directly replaces the original Titan part number 0551535. This spacer is engineered to fit Advantage 400, Advantage 500, and PowrLiner 1800M and 2800M models. Its primary role is to ensure that components such as gears, bearings, or shafts are held at the correct distance from one another. Proper spacing is critical for smooth operation, as it prevents unwanted friction, misalignment, and premature wear. Over time, spacers can be lost during disassembly or may become damaged due to corrosion or mechanical stress. If a spacer is missing or the incorrect thickness is used, the resulting end play or binding can lead to noise, vibration, and accelerated failure of expensive parts like gears or the pump housing. Replacing a worn or missing spacer with the correct 806-091 component restores the original factory tolerances. This helps ensure that the drive train operates quietly and efficiently. When servicing equipment that uses this spacer, it is advisable to inspect the mating surfaces and related hardware for any signs of wear. Using the genuine replacement part guarantees the correct dimensions and material properties for long-lasting performance.
